聚合物 - 在模板中迭代对象 [英] Polymer - Iterating over object in template

问题描述

根据聚合物文档，可以迭代对象或数组在< template> 中使用重复语句：

According to the polymer docs, an object or array can be iterated over using the repeat statement in a <template>:

expression可以是简单的标识符，路径或完整表达式（包括Object和Array文字）。

"expression" can be a simple identifier, a path or a full expression (including Object and Array literals).

然而，在测试之后，似乎repeat语句只适用于数组，而不适用于对象：

After testing, however, it seems as though the repeat statement only works with arrays, and not with objects:

我做错了什么？

推荐答案

那里的文档是不精确的。表达式的一般性质是明确的，但我不认为它打算说你可以迭代重复对象。

The docs there are imprecise. The general nature of expressions is explicated but I don't believe it intends to say you can iterate over objects with repeat.

我相信只有Arrays支持迭代时间，虽然有人说可能支持NodeLists。

I believe only Arrays are support for iteration at this time, although there is talk of possibly supporting NodeLists also.
